"TheJamesRolls and L8RG8R2U battle it out in this ultimate adventure!"
- L8RG8R2U was ahead of TheJamesRolls in the 3rd book by quite a lot, but James was able to make a comeback and eventually win due to G8R's inability to find the Golden Mushroom required for the secret mission in the final level
- In later series between James and G8R, G8R proclaims that any project they do he automatically wins due to beating the Mummy-Me Maze Forever level first. James pulled a similar gag in Splatoon 2 Versus after talking to Marie first after the credits sequence following the single-player campaign
